Another celeb marriage is coming to an end, although this one seems to have been a long time coming. Amy Winehouse’s husband of nearly two years, Blake Fielder-Civil, is filing for divorce from the singer “on the grounds of Amy’s adultery,” said his lawyer, Henri Brandman. The couple has had a rocky relationship, made even more difficult when Blake was arrested in late 2007 for assault and then sentenced to 27 months in jail for trying to bribe his victim. He was released in November to a drug rehabilitation center but was placed back in prison for not meeting his bail requirements. Amy, who’s had plenty of problems of her own, has been linked with Josh Bowen while she vacations in the Caribbean. Will this turn into an another ugly courtroom battle?
